Not only have you proven that you didn't read the article, but that you also have absolutely no understanding of archeology, or the various methods of how they dertermine the age and origin of bones.
Firstly, allow me to point out to you that
fossilised rock and
fossilised bone are
completely different. Bone and rock have no similarities, whether fossilised or not, other than consisting of carbon.
I'm assuming that you don't know what these means, so I'll explain it to you like your a child.
A long, long time ago, Pennsylvania was covered in water!
I know this is hard to believe, but theres proof! When it was covered in water, the bottom was made up of mud and rock. With these things called "currents" (the movement of water) and perhaps even such things as earthquakes and volcano's, new mud and rock is swept into the water! This new mud and rock slowly sinks to the bottom, and coveres the new mud and rock. Over millions and millions of years, as the planet changed, more and more new mud and rock were brought in to the water, and sunk to the bottom, creating more new layers of mud and rock at the bottom of the water. As the "tectonic plates" moved, the land was pushed up and moved, and the water went away, leaving the bottom of the ocean as the new land! Through further movement of wind and rain, even more new layers of mud and rock were added.
Now, when a prehistoric animal died (such as this tetrapod fossil), its bones are left in the ground. Because there were no people back then to pave cement walkways or build office blocks, there was nothing to move the bones. Because of this, during the process of the new sedimentry rock being layered, the bones would get stuck under the ground.
Now, when these guys in Pennsylvania were laying down this new road, they had to cut into the ground. When doing so, a bone was found in a rock. (Remember, bone
is different to rock)
When it was analysed, scientists can do this nifty technique called
carbon dating. This isn't taking carbon out to dinner and a movie - it's where scientists can find out how old something is. When they checked this with the layer of sedimentry rock it was found in, they realized it was when the land was covered in water. By relating this to perviously known dated information on found fossils, it was deduced that the creature the bone came from was alive, was before land walking animals. From this information, it can be assessed that the creature lived in the water. These scientists also can examine the bone fossil to discover where the bone came from in the animals body. This can be deduced from analyzing samples of other fossils, as well as modern day animals.
In conclusion, learn something about the topic you are going to claim to be "bull****", before making an *** out of yourself again.
